. E NVELOPL SPECIFICATION forming part of Letters Patent No. 751,423,dated February 2, 1904.

Application filed December 24,1902. Serial No. 136,507. (No model.)

' to the accompanying drawings.

This invention relates to envelops primarily intended for use in mailingsmall articles of merchandise or advertising matter, and has for itsobjects to provide ablank of novel form adapted to be folded to producean envelop that will secure within it small articles of mer-' chandiseor other articles in such manner as to effectually prevent them fromfalling out and at the same time permit the envelop to be readily openedto allow the articles to be withdrawn.

A further object of my invention is to provide a construction that willpresent a large amount of surface suitable for advertising purposes thatwill be brought into viewwhen the envelop is opened, but will not bevisible when the envelop is closed.

I attain these objects by the construction shown in the drawings andhereinafter specifically described.

That which I believe to be new is set forth in the claims.

In the accompanying drawings, Figure 1 is a view of the blank from whichthe envelop is formed. Fig. 2 is a perspective view showing the longstrip portion of the blank partially folded. Fig. 3 is aperspective viewof the completed envelop in its closed position, showing its rear side.Fig. 4 is a front view of the envelop closed. Fig. 5 is a perspectiveview of the envelop, showing its rear side and showing the long stripportion withdrawn from the body of the envelop, but partially folded;and Fig. 6 is a view similar to Fig. 5, but with the projecting portionof the long strip extended its full length from the body of the envelop.

Referring to the several figures of said drawings, A B indicate theblank from which the envelop is formed, the part A consisting of arelatively long strip of paper and B a side extension at one end of thestrip A, such side extension being in the construction shown a littlelonger than the width of'the strip A, such additional length beingprovided so that when the blank is folded into envelop form, ashereinafter described, the outer end may be turned over the" edge of thestrip A and secured against the back of such strip, such narrow partthat is adapted to be so turned over being provided with mucilage orequivalent securing means. This end of the extension B that is securedagainst the back of the strip A is indicated by a.

b, o, and d indicate the lines of fold in the strip A, and e the line offold of the extension B, which latter fold is given the blank after thestrip A has been folded up.

In use the articles to be inclosed are to be placed on that portion ofthe strip A between the lines 6 and c. The strip A is then to be turnedupon itself along the central line b, af-

escape at the two other sides; but by folding the extension B along theline 0 and over the folded strip A one of these open sides is closed,and by bending the projecting end a" over the opposite edge of thefolded strip A and securing it against the back of such strip theremaining open side of the space in which the articles are located isclosed. The envelop' is thus formed, and by reason of the folding of theblank in the manner specified the articles contained therein areeifectually held, but can be readilyremoved without destroying theenvelop by grasping that end of the strip that forms the lower part ofthe piece A of the blank and pulling outward from the upper end of theenvelop. This can be readily done, for in the completed envelop suchlower edge of the strip A lies adjacent to if not directly opposite theupper edge of the strip A. This end is to be pulled out until what wasthe part A of the blank remains folded only along the line 0,consequently exposing above the edge of the envelop all that part of thestrip A that when in the form of a .blank isbelow the fold b. Theexposure of so much of the strip furnishes very desirableadvertising-space, which is a feature of very considerable value inconnection with envelops adapted for mailing small articles ofmerchandise. Either or both sides of such exposed portion of the stripcan be utilized, as desired.

By my invention I provide a device in which small articles ofmerchandise can be easily and quickly inclosed in a form of package thateffectually prevents their accidental escape therefrom and at the sametime is not of such a character as to subject the package when mailedwith only merchandise therein to postal rates greater than that providedfor such matter; that can be readily opened without destroying theenvelop; that presents a large surface for displaying advertising matterwhich can hardly fail to be observed immediately upon the envelop beingopened, and that can have the blank from which itis formed out out withpractically no waste of stock.

As will be understood from the foregoing description, it is theintention that the articles be placed upon the blank and the envelopformed in the manner described around such articles, which is thepreferable manner of using the device; but the envelop can be firstformed, if desired, and the articles then placed therein; but thislatter method of use will generally not be found so satisfactory, it isbelieved, as the use in the manner described.

The lines of fold-viz., the lines marked 6,

0, (Z, and emay be indicated on the blank by printed lines or by actualfolds imparted to the paper prior to the sale of the blanks to the user,or directions as to the manner of folding the blank may be printed uponthe blank.

That which I claim as my invention, and desire to secure by LettersPatent, is

1. An envelop comprising a strip having a side extension, said stripbeing folded upon itself to bring its lower edge adjacent to its upperedge,then being again folded upon itself to bring its central portionadjacent to its up per edge and form four thicknesses, and then havingthe side extension folded over said four thicknesses and fastenedthereto, the lower edge of said strip being exposed at the upper end ofthe completed envelop so that said lower end can be drawn out to openthe envelop.

2. An envelop comprising a strip having a side extension provided with aflap, said strip being folded upon itself to bring its lower edgeadjacent to its upper edge, then being again folded upon itself to bringits central portion adjacent to its upper edge and form fourthicknesses, then having the side extension folded over said fourthicknesses, and having the flap thereof folded around against theopposite side of said four thicknesses and pasted to the outer layerthereof, the lower edge of said strip being exposed at the upper end ofthe completed envelop so that said lower end can be drawn out to openthe envelop.
